Fiberglass Form Ties Projects


Sigma 400 Series fiberglass form ties have been used in a variety of cast in place applications. Here are some site pictures just to give a small sample of what has been done with our 400 series tie.


Sigma 1000 Series ties have been used in large heavy duty forming applications in place of she bolts and taper ties. A big reason for using Sigma 1000 Series fiberglass form ties is the cost related to stripping and finishing thick sections such as bridge abutments, diaphragms, pier caps. With the 1000 Series Tie, you simply grind the tie flush to the face and you are finished. There is no plug, patch, or other finish work required. On these thick sections, the removable steel ties could get stuck and then would need to get cut out along with chipping around the concrete to get the appropriate depth of cover on the patch. These trouble ties cost large sums of time on money the job site. There is zero issue with the Sigma 1000 Series. They were the tie of choice for Kiewit/Weeks/Massman joint venture on the Goethals Bridge in NY/NJ.
